Many Exynos devices have a display panel. Most of them just have
a simple panel while others have more complex configurations that
requires an embedded DisplayPort (eDP) to LVDS bridges.

This patch enables the following features to be built in the kernel
image to suport both setups:

- Direct Rendering Manager (DRM)
- DRM bridge registration and lookup framework
- Parade ps8622/ps8625 eDP/LVDS bridge
- NXP ptn3460 eDP/LVDS bridge
- Exynos Fully Interactive Mobile Display controller (FIMD)
- Panel registration and lookup framework
- Simple panels
- Backlight & LCD device support

Could you please also do corresponding update to multi_v7_defconfig?

As was mentioned in v1 (but now below), some of these options depend on
patches yet to be respun and be accepted into drm, so I would consider
this an RFC patch and suggest to wait with multi_v7.

It could of course be split, as CONFIG_DRM_EXYNOS* and backlight parts
are certainly okay.

Andreas

Changes since v1:
 - Forgot to enable ptn3460 eDP/LVDS bridge config option
   which is used for some boards (e.g: Exynos5250 Snow).
